Making the case for the #CorsiRosenthalBox with studies.

A simple thread.
"no U.S. Energy Star certified air cleaners have CADR values (for either tobacco smoke, dust, or pollen) matching the CADR value for the CR Box even on low speed "

On cost? 1/10th.

1019 to 1444 m3/hr CADR.

(600 to 850 ft3/min)

Published here:
tandfonline.com/doi/full/10.10… ImageImage
An incredibly thorough study published in February 2023, with all of its authors from @NIOSH.

With universal masking in a 3-ply cotton mask, exposure to the relevant aerosol size is reduced by 88 to 94%, with the #CorsiRosenthalBox.

73% w/ CRBox alone.

sciencedirect.com/science/articl… ImageImage
Very good thread on this study here:

Essentially the same NIOSH team investigated HEPA efficacy.

65% reduction with HEPA alone.

So, at a much cheaper price, the #CorsiRosenthalBox gets better results.

cdc.gov/mmwr/volumes/7…
But can HEPAs remove SARS-COV-2 from the air? Yes.

(Would #CorsiRosenthalBox do the same? Yes - faster and cheaper.

Has it been studied specifically for this? No. HEPAs barely have.

Do the same laws of physics apply? Yes.)

journals.asm.org/doi/full/10.11… Image
But can HEPAs really remove SARS-COV-2 from the air?

Yes - in a UK hospital, HEPAs were off. Cov1d was in the air. Turned on. No more CoV1d.

1000 m3/hour CADR.

Remember the first study?

1019 to 1444 m3/ hour for the CR box.

@MarinaC_Dyb and her fellow authors found a massive reduction in aerosols in OCCUPIED classrooms using the #CorsiRosenthalBox. Also found that ALL of the air went in.

No wonder they have rolled them out to 400 locations.

Study is linked here:

Oh for Pete's sake. @elonmusk has just killed another thread.

Let me add these manually.
"Also found that ALL of the air went in" - quoting above to go into a little more detail:

This answers, in a study, the concern that it just moves the air around. That it won't go into the filter.

It does, and this had to be pointed out.
The CDC, of which NIOSH is part of, has officially recommended 5 ACH, minimum, and that DIY Air Cleaners are effective at reducing the risk of transmission of Cov1d.

The #CorsiRosenthalBox is
specifically mentioned as part of that solution.

cdc.gov/coronavirus/20… ImageImageImage
@3M has studied it in their formal lab - and is officially on board:

news.3m.com/2022-02-24-3M-…
The famous UL, Inc testing the safety of the #CorsiRosenthalBox, to make sure it won't catch on fire.

It won't - even if the filters are loaded up.

(The link that is out on Twitter appears to be dead.)

ul.org/library/2988
"Does Using Corsi–Rosenthal Boxes to Mitigate COVID-19 Transmission Also Reduce Indoor Air Concentrations of PFAS and Phthalates?"

Yes.

pubs.acs.org/doi/10.1021/ac… Image
Some have expressed surprise that this was found.

Dr. Corsi explains:

And the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRi
A thesis - a study, that found 7 PFAs, and exposure to for both dog and human. (@ShellyMBoulder collaborated).
elischolar.library.yale.edu/ysphtdl/2161/ Image
How do we know that dogs are affected? Because it is dogs that get experimented on.

And not to get too personal, but my dog has stage 4 chronic kidney disease. CKD can be caused by PFAs.

Did I do that? Or at least not prevent it? A lot of

wunc.org/health/2021-05… Image
years with no air filtration.

But hey - she is 15 years old, and it could be just old age.

In any event, I don't want to go into any more detail, but now I know better.

But besides PFAs, dogs can catch Cov1d.

As can cats.

In fact, from the study, we should see our cat as part of our family regarding virus transmission.

Can a cat or dog wear a mask?

Yes, with training.

But what if you could reduce their risk of catching Cov1d without all that? Image
And the risk to the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRosenthalBox as the centerpiece of your family pandemic prevention protocol.

And it worked.

@TheAtlantic @danengber Heh - I suspect Mr. Engber has been eavesdropping on my (and my fellow Covid Conscious) swimming safer threads. I have a new solution for showering safer for that I will be rolling out tomorrow.

For future articles by those who will come along, let me point out a few things /+
@TheAtlantic @danengber Thank you very much for pointing out that 4% of America is still masking 100% of the time! That is 13.2 million Americans.

The Masking Nation is larger than 38 states. :)

But, 18% of us masking some of the time in the SAME PEW POLL (tch tch). You would think that would be/+ At a basic level, their COVID-conscious attitudes may not be so far from the mainstream. Twenty-one percent of Americans still think of the disease as “a major threat” to public health, according to a recent poll from Pew Research Center. Thirty-nine percent say we’re not “taking it seriously enough.” But if 50 million to 100 million adults harbor such concerns, very few are doing much about them. Masking rates were once as high as 88 percent; now they’re close to nil. For those who still maintain their masking habit—4 percent, says Pew—the whiplash in social norms has been a shock.
@TheAtlantic @danengber be mentioned, @TaylorLorenz, by Mr. Engber, since 18% lines up pretty closely to the 21% still worried that Covid is a big deal (it is) - that he mentioned.

And suddenly, Masking Nation has 59.4 million residents. We are the largest state. Canada /+

This may be one of the most important studies in a decade.

#LongCovidBinder.

"The models produced correctly classified those with severe ME/CFS from recovered controls with an accuracy of 97%, sensitivity of 94%, and specificity of 100%. "

THAT IS HUGE.
"We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. " We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. IL-5 enhances the production of B1 cells which are anti-inflammatory (impaired B1 cells have been found in multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis), and IL-13 has anti-inflammatory properties. Jason et al. [26] also found that students who failed to recover from IM had more restricted, inflexible cytokine networks whereas those who recovered had more flexible, less interconnected networks. Network analysis suggests that IL-5 and IL-13 influe...
So, this means ME/CFS can be predicted.

And what can be predicted - treatments can be found.

And they are studying LongCovid as well.

This study is easy to read, And everyone should.

A new study just showed what I have been saying since the start of bird flu. H5N1 is airborne.

Still in place?
USDA: YOU ONLY NEED TO TEST LACTATING COWS.

oops.

USDA: FOMITES (infectious objects) SPREAD IT.

oops.

WASHING YOUR HANDS WILL STOP IT.

oops. This new Federal Order does not override or supersede USDA's April 24 Federal Order, which still requires the mandatory testing of lactating dairy cows prior to interstate shipment and requires that all privately owned laboratories and state veterinarians report positive test results connected with those tests. The new Federal Order announced today is intended to complement and enhance this existing order.
Question [00:51:52] Given the CDC's vaccination program, I'm wondering if this means you think it's no longer realistic to expect that the outbreak will be contained this year? Eric Deeble, USDA [00:52:12] Just on the animal side and all that Dr. Nirav speak to the human side, there's a lot about this disease that makes us feel as if we can arrest its progress. And we've actually seen some success demonstrated to date. With this disease, it does not appear to move by respiratory transmission. We know that there are high viral loads in milk, and we've identified through close, collabora...
In addition to testing, biosecurity is the key to containing this virus, and ultimately ensuring that it is eradicated so that producers do not have to deal with this virus in dairy cattle permanently. Good biosecurity including cleaning and disinfection of vehicle and equipment - is critical to minimizing the risk of disease spread. USDA works closely with state animal health official, producers, and industry organizations to provide guidance and resources for cleaning and disinfection not only on affected farms but for all livestock producers as a part of practicing good biosecurity. APHI...
The study.

✅ 20% of the cows showed up as sick. Had symptoms. But....

✅ It turns out that 89.4% were actually infected.

✅ 83.7% of those had no symptoms. Remind you of any other airborne diseases?

✅ 40.5% of the dry cows not being milked? Infected. So, no Image

fomites or milk aerosols involved, most likely.

There is not much that scares me. Freaks me out.

I am freaking out.

You should be, too.

Do you know what this shows?

Do you know how to avoid this? Holy cow.
This is the continued accumulation of dementia-causing microplastics in your brain. Simple linear regression (shown with 95% CI represented by dashed lines) was performed for total plastics, polyethylene, polypropylene, polyvinyl chloride and styrene-butadiene rubber measured in normal decedent brains from 2004 (average of east coast samples), 2016 and 2024 (NM OMI samples).
See how it increased from 2016 to 2024?

And it actually is worse - they found less plastics in brains from a decade earlier.

Great interview of Ed Yong - I am just covering the C0V1D part.

/1 The Interview Ed Yong Wants to Show You the Hidden Reality of the World Ed standing with his arms folded. His eyes tell you COVID is not over.
You've been clear in saying that C0V1D has not gone away. You ask people to wear masks at your events..... You’ve been clear in saying that Covid has not gone away. You ask people to wear masks at your events. But that attitude is not necessarily where the rest of the world is. How do you think about continuing to take precautions and advising others to do so when it feels as if society has moved on? I do it for a bunch of reasons. Firstly, I have learned that I enjoy not being sick. I know that the cost of long Covid is real and substantial, and I don’t want to run that risk lightly.
"I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird." . I also know that I have many friends and people I’m close to who are immunocompromised. So for the sake of the people around me, I also don’t want to get sick. When I do events, I wear a mask for those reasons, and because I know that every time I do a talk, while the vast majority of people in the audience have probably moved on, there are going to be other people who haven’t. I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird. So I do it for that reason, too. In terms of holding this line at a point when a l...

I am sorry if this will upset you. A lot of people depend on NASAL SPRAYS for C0V1D.

I have been iffy on them, but viewed them as "if they don't hurt, why not" but not for me.

There's an analysis
on Reddit that you should read in detail, and make up your own mind.
/1
Here is the link:


Here is a 4 tweet TLDR version.

Here is how it starts - the author goes HARD at the underlying studies. reddit.com/r/ZeroCovidCom…There is no convincing evidence that nasal sprays prevent COVID-19 There is a lot of misinformation out there about nasal sprays preventing COVID-19. Unfortunately, there are no convincing studies showing that nasal sprays prevent COVID-19. The published studies investigating whether or not nasal sprays prevent COVID-19 each have major issues, which I will detail here. I have a PhD in biochemistry and one of my PhD projects was on COVID-19. The main takeaway of this post is that there is no sound evidence that nasal sprays prevent COVID-19. Thus, nasal sprays should not be used for COVID-...
Some pretty harsh language, but to me the important thing is we still have clean air.

Which is good, because it boils down to only 2 studies saying that nasal sprays work, per them. 5. Summary/TLDR and final thoughts Unfortunately, many people including covid influencers have fallen for the grift of nasal sprays preventing COVID-19. Some such influencers have promoted these nasal sprays for free and helped spread the misinformation that they prevent COVID-19. Unlike with nasal sprays, there is ample, sound evidence that high-quality well-fitting respirators, ventilation and air purification prevent COVID-19. The human clinical trials testing whether or not nasal sprays prevent COVID-19 are garbage, and to my knowledge there are only two! Please don't lower your covid...
